@ All,
If we're going to pulse our coils the the link the I posted the other day is one of the simplest that I've seen.
http://www.cpemma.co.uk/555pwm.html don't know the guy and have no association with him other than liking his site.
If you have a jouel theif you already have a pulsed power source. Take the carbon and steel rods that we've all been playing with and feed the jouel theif and feed the Stubbelfield coil primary and see what you can get out of the secondary.

The voltage seemed to peak out for me at .9 v almost a volt


For large readings this thing should be long and thick Thinking a real model would have been a foot and half tall and probably 3/4 of a foot wide.  Im going to go for one half those dimensions next, remember thats including the secondary wind too, as well thats why im using thick steel wire/iron not sure acctualy  and large solid copper, i figure it would take the space up easier and he says whatever gauge wire you want to use.. but its obvious there big.  I think the secondary may be wound with the same gauge copper you use for the primary but you can use the regular peice of romex wire with the plastic insulation on it , they say mica or celluoid insulation but i think the regular plastic will be fine for the secondary.  Anyone Know what mica or celluiod insulation might have looked like back then?

I have been  reading  past posts on this thread

I still have quite a few to go .

Is anyone here still looking for carbon rods?

I bumped into some on  ebay

Your kinda right but not completly.

The primary coil is the power source it creates voltage, so we dont need a power source to pulse the primary.. We need a mechincal device to make and break the connection of the primary to it self ..

so the pulsing is only say you touching a copper and iron wire together and apart together and apart. 

My gut says the easiest way to do this is a small hobby motor with a thin plastic disc or wooden disk attached to it with 4 strips of foil cris crossed on the top and extending to the edge and over it.

So picture this little motor with the disk horizontal and a terminal from each wire on either side of it just barley touching the disk. when you turn the motor on the disk with foil will make and break the connection for you and all we need is a little pot . potentiometer or variable resistor so we have a knob to physically control the speed it makes and breaks the connection.. this should be the most effective to start, i dont want to try the 555 yet i really want a mechanical solution, to just secure minimal results with proof of concept then we can go ss but until we know it mechincally works like we want it we'd be pissin in the wind with a 555 timer or any other ic.  Im going this slow with each phase of this because I really feel it helps us all understand the nitty gritty conceptes behind this stuff. lets not make the mistake the tpu people did.... They could have been where otto is now log ago.... Focus folks.   I'm very proud of everyone and excited!  Make sure you ask about anything your unsure of because no question is ever stupid..

rat's nest of themselves and were twisted together.  It would be nice if we could make a spool feed rack to allow the wire to roll of the two spools as we need it.

I think it's great when people post their pics of their efforts. 

  I am really enjoying this.

I am really enjoying this too.

Try this for the spool holder. Put your 2 spools around a paper towel cardboard (or short piece of plumbing pipe) then feed a string through the inside of the same cardboard tube/pipe and hang it all from something.

@all, Woven cloth is easy to tear straight cuz of how it is made. Just clip 1/2 in at the edge to start it and RIP. It is best if you rip it fast.  (The dielectric properties of silk are made aparent by this action! )

@all
If the dielectric properties of an insulator are important then why do you get it wet? doesn't wetness stop the dielectric action of the cloth? This is a theory question and has nothing to do with my building today, but I am thinking along these lines a lot.

I will post 2 pics of my spike. first is the spike with silk covering the spike and one round of 2 wires.  Second is how it is now after 3 1/2 rounds which is where it was at the end of the copper wire.
